BOTTLE-STOPPER.

To all whom it may concern:

Be it known that we, MARK LOUIS ORR and FINGAL CECIL ORR, both subjectsof His Majesty the King of Great Britain and Ireland, residing at Amana,Stillorgan, in the county of Dublin, Ireland, have invented new anduseful Improvements in Bottle- Stoppers, of which the following is aspeci fication.

This invention has reference to stoppering bottles of that class inwhich the mouth of the bottle is made with an internal annular grooveand the stopper is made in the form of a disk like cap or domed ortruncated conical shape in cross section with a wad of cork or othersuitable substance underneath so arranged that when these are placed inthe bottle neck with the wad resting on a shoulder therein forming thebottom side of said groove and the said cap is by a suitably formed toolpressed into a flatter form it is thereby expanded in diameter andengages in the groove in the bottle neck and thus with the wad issecured therein so as to stopper the bottle but often very imperfectly.

Our invention consists of the improvements herein described in theconstruction and arrangement of the metal cap and its wad or liningwhereby the stoppering is rendered perfectly tight no matter whatpressure of gas there may be in the bottle.

We will describe this invention by referring to the accompanyingdrawings on which- Figure 1 is a sectional elevation of the upper partof a bottle neck which is stoppered in accordance with this invention;Fig. 2 is a sectional elevation and Fig. 3 is a plan of the stoppershown in Fig. 1 before being inserted and pressed in the bottle; Fig. iis a sectional elevation of the stopper in the bottle neck ready to beflattened to close the bottle; Fig. 5 is a sectional elevation of a.slightly modified form of stopper and Fig. 6 is a sectional elevation ofthe upper part of a bottle neck made with a modified form of groove andshowing the stopper Fig. 5 in position ready to be compressed into thegroove by the punch which is also shown partly in section.

For the purpose of this invention there is formed around the interior ofthe bottle mouth and near the top of the same a V-section annular groove1 which has one side 2 Specification of Letters Patent.

of the V preferably although not necessarily sloping downwardly andoutwardly (Figs. 1 and a) from the entrance 3 into the bottle neck sothat the apex t of the V is well below the bottle mouth or entrance 3,or as shown in Fig. 6 the side 2 of the V may be flat or square with thebottle mouth. The other side 5 of the V slopes upwardly from E the apexof the V so that the diameter of the side 5 of the groove is graduallydiminished toward the top 6 of the bottle.

In carrying out this invention the stopper cap 7 is stamped from a thinsheet aluminum blank or is made of other suitable metal and preferablyof a domed shape as shown in Figs. 2, l and 5 with the upper partdepressed at 8, the diameter of this stoppering cap being very slightlyless than the smallest diameter of the portion 13 of the bottle neckwhich is formed by the side 5 of the V-shaped groove. This cap hasunderneath it a fixed or separate disk shaped lining 9 of any suitablesoft waterproof material preferably what is known as vegetableparchment, or cork or card, or other suitable material faced withvegetable parchment, or the lining may be cork or indiarubber or othersuitable substance without the vegetable parchment facing, but itsdiameter has to be somewhat larger than that of the metal cap as shownin Figs. 2, 3, at, 5 and 6 so that the periphery 10 of this liningprojects all around beyond the periphery ll of the cap 7, and ifdesired, may, as in Figs. 5 and 6 be turned up over and around theperiphery of the metal cap 7.

The disk like lining 9 with the cap 7 above it are placed in position inthe bottle neck so that the periphery 10 of the disk like lining 9 restson the lower side 2 of the V-shaped groove as shown in Fig. at and thenwhen the disk like cap is pressed down and somewhat flattened by thepressure of a suitable punch like tool such as shown in Fig. 6 andmarked 12, said disk like cap will be expanded in diameter and its rimor edge 11 will dig into the portion of the lining 7 which projectsbeyond the periphery of the same and force the lining down and jam itinto the angle 4 of the V-shaped groove as in Fig. 1 so that theperiphery of the disk will be embedded in the lining and a perfectly airand liquid tight joint will be formed, and owing to the side 5 of the Vsloping upwardly toward the center line of the bottle and its diametergradually decreasing it Will be impossible for the internal pressure inthe bottle to raise the cap and lining out of the angle of the V-shapedgroove and thus the bottle will remain tight under all pressures. Thecap and lining can readily be withdrawn by first forcing a corkscrewthrough them and to facilitate this the metal disk 5 may if desired bemade with a small central hole, although such hole is by no meansnecessary if the metal cap is, as we prefer, stamped out of thin sheetaluminum.

Our objects in making the groove in the bottle V-shaped and arranging itas above described are firstly so that while the cap and lining arebeing forced thereinto in the flattening process above described. thefarther they enter the groove the more tightly the cap and lining willbe pinched by the inclined sides of the groove as they approach theangle 4. of the V, and secondly the V- shaped groove can be made deeperthan would be expedient or possible if it were made with square sidesand with the bottom side horizontal as in the known bottles and moreoverthe V-shaped groove when made with the side 2 inclined as in Figs. 1 andat affords a greater bearing surface for the cap and its lining and canbe made deeper than the flat groove will allow without weakening thebottle neck.

If desired the periphery 11 of the cap may be rounded by being turned upas in Figs.

and (3 to prevent it from cutting the periphery ll) of the pad or liningwhen eX- panded by flattening as above described.

lVhat we claim as our invention and desire to secure by Letters Patentis 1. The combination with a bottle made with a V-shaped internalannular groove of r a V-shaped internal annular groove, consisting of animperforate domed sheet metal stoppering cap, an imperforate lining forsaid cap having its edge turned up around the periphery of the cap andadapted to be forced into the angle of the V-shaped groove in the bottleneck by the flattening of the cap when placed therein.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing Witnesses.
